I Turned ARAM Mayhem Into A Horror Game With "Ultimate Awakening" Karthus 💀

The enemy team literally couldn't play the game in this ARAM Mayhem match! We hit an insane 880 AP and a legendary 307 ABILITY HASTE on Karthus! By combining Ultimate Awakening and Eureka, our AP scaled our Ability Haste to astronomical levels, letting us spam Requiem constantly. To make it completely toxic, "It's Killing Time" added massive burst scaling to our global ultimate, and Magic Missile automatically launched a barrage of heat-seeking projectiles at every single enemy on the map the moment we pressed R! If you roll Karthus in ARAM Mayhem, this is the ultimate exodia build you need to fish for! What is the highest amount of Ability Haste you've ever reached?
